Description

[Detailed description of the invention] The present invention relates to a reaping and tying machine for harvesting rice, wheat, etc.

In this type of reaping and tying machine, by making the tying passage and the single-row pulling path approximately perpendicular to form an L-shape, pulling and tying the reapings can be carried out smoothly over the shortest distance, and the overall length of the machine can be shortened. It becomes possible to achieve downsizing.

Furthermore, if the bundling passage is raised and configured to be narrower than the path,
At the time of raising, the planted shell culm is taken in.The stem base of the culm is reliably focused and supported in the relatively narrow binding passage, allowing for undisturbed binding.

By the way, if the running wheels of the above-mentioned reaping and tying machine are made into a single-wheel type, and this wheel is raised at approximately the center position in the longitudinal direction of the machine body and installed at the rear of the path width, the machine body can be made even more compact.
The wheels run on the stubble, which improves wet field performance and improves the front-to-back balance. However, the heavy binding device is located closer to one side of the fuselage, making it difficult to move the binding device and culm. Due to the weight of the handle, the handle tends to be pulled to one side, and the mowing marks tend to be slanted.

In addition, because the wheels run on stubble that has been cut diagonally, the aircraft leans more and more to one side, making it extremely difficult to maintain left-right balance and hindering straight-line performance. Therefore, an object of the present invention is to provide a reaping and tying machine that has excellent maneuverability and straight-line performance while taking advantage of the advantages of the conventional structure.

Next, the embodiment shown in the drawings will be described.

Fig. 1 is a side view of the entire reaping and tying machine, and Fig. 2 is a plan view thereof. A clipper-type reaping device 3 is provided in the lateral direction of the body on the base side of the bodies 2, 2, and a pulling device 8 is installed in the gap between the sled bodies 2, 2 to form a path 7 for pulling the shell culm. One side of the lifting case 4 constituting the pulling device 8 is attached to a clipper type reaping device 3.
The culm lifting protrusion 5 is provided diagonally in the left side of the fuselage in the front-rear direction with a lower front and back height, and the culm lifting protrusion 5 is provided so as to be able to move in and out of the case as in the conventional structure. A conveying space is formed between the rear end of the lifting guide plate 6 and the shell culm guide plate 1, facing the lifting case 4, and is installed obliquely on the right side of the clipper type reaping device 3. On the right side of the reaping device 3 and on the side of the machine, a binding transmission case 9 is fixedly installed below, and a binding device 12 consisting of a knot 11 similar to the conventional structure is constructed on the upper part of the case 9. A binding passage 10 extending laterally into the binding device 12 from the rear of the device 3 to the right end of the machine body is provided at the upper part of the reaping device 3 in the lifting path 7 in the longitudinal direction of the machine body passing approximately at the center in the width direction of the machine body. The rear part of the reaping device 3 and the bundling passage 10 are configured to form an L-shape in plan, and a culm guide plate is installed upward from the rear of the reaping device 3 and the bundling passage 10 and extends toward the rear of the machine. The width 1 of the binding passage 10 formed by the side guide member 11a and the support guide plate 1 is made narrower than the width L of the passage 7.

A transmission gear housing 14 is installed on one side of the left side of the machine body, which is the rear side of the lifting case 4, and extends in the longitudinal direction of the machine body. 1
A running wheel 13 is installed, and the running wheel 13 is located approximately in the center of the machine body in the longitudinal and lateral directions, and is located at the rear of the raising path width L. The running wheel 1 is installed close to the rear of the culm guide plate A and is on the opposite side of the transmission gear housing 14.
The right side of 3 is completely open to the right side of the fuselage, and the right side of the running wheel 13 is wider than the open end of the bundling passage 10 and the right end of the culm guide plate A. It is placed so that it looks toward the center of the direction.

Further, the front end opening of the transmission gear housing 14 is cut off from the frame 1.
An underframe 16 is fixed to the rear end C of the machine, and the prime mover 15 mounted on the underframe 16 is moved to the left side of the center of the width of the machine at the rear close to the running wheels 13. The motor pulleys 7 and 18 are coaxially provided on the left side of the motor 15, and the main shaft 19 is protruded from the left side of the transmission gear case 14, and the main shaft 19 is provided in the transmission gear case 14. The main shaft 19 is provided so that transmission is transmitted from the main shaft 19 to the axle 23 via a group of transmission gears 22 on the horizontal axis.
from the main shaft pulley 20 fixed to the outer end of the drive pulley 17.
A driving pulley 24 is mounted above the reaping frame 1 by passing a belt a around it, and a belt b around the large pulley of the intermediate pulley 21 of the two-stage wheel loosely fitted on the main shaft 19 and the drive pulley 8. A belt c is looped around the small pulley of the intermediate pulley 21, and the drive pulley 1J24 drives each drive section in the reaping device 3, the inside of the lifting case 4, and the culm processing mechanism of the binding device 12.

25 is a raking wheel provided above the reaping device 3, and 26 is a weeding body.

When the prime mover 15 is started, the drive pulley 17 is transferred to the main shaft pulley 20 via the belt a, and further to the main shaft 19.
The power is transmitted to the transmission gear 22 group, the main shaft 23, and the running wheel 1.
3 rotates on a unicycle, and on the other hand, a motorized pooh? river 8
It is transmitted to the intermediate pulley 21 via the belt b and further to the drive pulley 24 via the belt c, and the culm processing mechanisms of the reaping device 3, the pulling device 8, and the binding device 12 are respectively driven.

Therefore, when the machine moves forward with one running wheel 13, the culm planted in the field is moved by the lifting device 8 having the width L.
The root of the stock is cut by the reaping device 3,
The cut culms are guided by the culm guide plate A and transferred to the narrow tying passage 10, where they are tied by the binding device 12 and then moved to the right side of the fuselage, away from the culm guide plate A in the bundling passage 10. It is released onto the field on both sides.

In this case, even when the machine moves forward, the husks released into the field are left alone without being trampled or covered with mud because the running wheels 13 are retracted toward the center in the width direction of the machine. Since the side portion of the body on the right side of the running wheel 13 is completely open to the running wheel 13, the work of attaching and removing the running wheel 13 can be carried out immediately without any obstacles.

In addition, although the binding device 12 and the transfer space/binding passage 10 are located on the right side of the machine, the prime mover 15 at the rear of the machine is shifted to the left side of the machine, so the left and right balance is maintained.
The reaping device 3 can be kept substantially horizontal.

Therefore, the traveling wheels 13 travel on stubbles cut approximately horizontally, and the vehicle can proceed without being hindered in its straightness. Furthermore, the bundling passage 10 located downstream of the hoisting path 7 has a width 1 narrower than the hoisting path width L, and since a conveying space is formed above the binding device side guide member 11a, the conveying shell The base of the culm is reliably focused and supported, and at the same time there is no resistance to transport at the tip, so there is no shedding, and the culm body stands upright or tilts backwards, resulting in smooth transport of the culm as a whole and no disturbance. Unity will do the trick.

As described above, the present invention allows the binding passage formed by the binding device side guide member and the shell culm guide plate facing thereto to be formed in an L-shape so as to be substantially perpendicular to the single-row pulling path. In a reaping and tying machine in which the passage is raised to be narrower than the route, a single running wheel is installed at approximately the center in the longitudinal direction of the machine body, and the single running wheel is raised and placed behind the width of the route, while the prime mover is located at the rear of the machine body. By raising and deviating from the center of the path to the side opposite to the binding device, the following excellent effects can be achieved. The entire length of the machine is shortened to make it compact, and a small, lightweight and good reaping and binding machine with good running performance in wet fields can be obtained.

2. The relatively wide pulling path 7 allows smooth take-in of planted culms, and the relatively narrow tying path 10 allows reliable tying without disturbance, allowing smooth cutting and tying work.

3. In particular, the front-rear and left-right balance of the machine body is good, and maneuverability is improved, and since the running wheels 13 run on stubbles cut approximately horizontally, the straight-line performance of the machine body is also improved.
